IMPROVEMENT IN HAY AND COTTON PRESSES.

Specification forming part of Letters Patent No. 202,835, dated April23, 1878; application filed November 22, 1877.

To all whom it may concern Be it known that I, MAXIME LAHAUSSOIS, ofParis, France, have invented a new Improvement in Hay and Cotton Press;and I do hereby declare the following, when taken in connection with theaccompanying drawings and the letters of reference marked thereon, to bea full, clear, and exact description of the same, and which saiddrawings constitute part of this specification, and represent, in-

Figure 1, a longitudinal sectign; Fig. 2, a transverse section on line XY; Fig. 3, a transverse section on line Z V; and in Fig. 4 a section online K M.

This invention relates to an improvement in presses such as are used forpressing hay, cotton, and other substances.

In the presses, as hitherto constructed, the entire mass required for asingle bale has been placed in the press and the whole mass compressedat one time. In such pressing the portion situated at the surface ismuch more compact and dense than that near the middle of the bale.

The object of this invention is to make the bale equally densethroughout; and it consists in pressing the material in successivelayers, one after the other, and then combining the several layers intoone bale, as more fully hereinafter described.

The pressing apparatus consists of a pair of strong cylinders, G O,constructed with circumferential grooves, which serve as guides formetallic bands 1 t, the bands on the cylinder 0 passing around rolls Rand T, and those on cylinder 0' passing around the rolls R and T. Therolls are arranged distant from each other according to the thickness ofthe layer required, and supported in suitable bearings, so that powermay be applied thereto in any convenient manner. The bands ll" fromtheir respective cylinders pass in a horizontal plane to theirrespective rolls R R, the distance be tween the bands corresponding,therefore, to the distance between the rolls. t is the platform on whichthe material to be pressed is placed. The sides of the case whichincloses the rolls are made flaring outward, as seen in Fig. 4, and soas to form a funnel-shaped mouth or entrance between the rolls. Thematerial to be pressed is placed on the platform t, and directed betweenthe revolving rolls. The mass will be compressed to a thicknesscorresponding to the distance between the rolls, and in lengthcorresponding to the length of the rolls.

The collector, in which the successive compressed layers are to beintroduced, consists of a case in which compartments are arranged tosuccessively present themselves to receive successive compressed layers.The number of these compartments varies according to the number oflayers required to form the bale. This case, or compartments, is formedby a series of sheet-iron plates, P, resting at their ends on blocks 0,with a top above and bottom below, all held together by bolts d, as seenin Fig. 3. These blocks form the sides of the compartments, and can bevaried in thickness, according to the thickness of the layer to beintroduced, as also may the area of the plates. This collector or seriesof compartments is arranged at the discharge, or at the point where therolls R R deliver the layer, so that the plates lie in a horizontalplane, and so as to be moved upward or downward between the walls A andD and the two sides of the apparatus, thus forming an inclined space,within which the collector may be raised. A movable bar or plate, K, issuccessively introduced by the operator, or may be by mechanical means,into each compartment, as it comes before the delivery of the press, andso that the material passing from the press into such compartment willforce the plate K outward, the plate K thus forming one side of the compartment. On the opposite side there may be a device to cut oif thelayer from the mass, so as to more clearly deliver the layer into thecompartment, and form the other side of that compartment, then the plateK removed from that compartment and introduced to the next. Thecollector is raised into the inclosed space above by any suitable means,(here represented as a rope over the pulley P above,) until the nextcompartment is presented for the second layer, and so on, until all thecompartments are filled. To bind the bale, the walls A and D, as well asthe top and bottom of the collector, are made with grooves,substantially as in common bailing-presses, through which the bands maybe passed and the bale se curely bound, the inclosed space within whichthe collector stands, when full, being constructed so as to be opened toremove the bound material, substantially as in other I presses.

It will be observed that the collector is removed with the bale, thenthe nuts d and their bolts taken out, so that the blocks 0 may beremoved, as also the division-plates and the top and bottom of thecollector. The bale is then free, ready for market, the collector againput together to receive another succession of layers, to be in likemanner delivered and bound.

I claim- 1. The method herein described of baling hay, cotton, &c.,consisting in a succession of compressed layers delivered successivelyto a collector, and each layer held in its compressed 1 condition untilthe requisite number of layers are delivered, then bound into one commonbale, and substantially as specified.

2. In a baling-press, the combination of the two compressirig-cylinders,the carrying and delivering bands around them, a collector composed of aseries of compartments, arranged so as to be successively presented tothedelivery to receive the material compressed by the rolls and hold thesame until the compartments are successively filled, substantially asdescribed. 7

In testimony whereof I have signed my name to this specification beforetwo subscribing witnesses.
